These things bang!!! As you know these are now contracted out to the military and even civilians love them. They are a piston system so they run cleaner than a gas system. I have a few other piston systems and never clean them.
This one has a silencer co lower with flaired magwells and an sig brace. Also has a rise aftermarket trigger IYKYK… they are not binary just to be clear. Just great triggers.
